Question about markings on Campagnolo Bottom Bracket axles.
I have a NR bottom bracket axle which is marked
68 -- SS -- 120 Z
The top line I understand.
The Z, I do not. What does it mean?
Next, anyone have such an axle to spare? I'd like to replace mine, due to a small pitted area.
Awaiting illumination,
